Abstract

Iron (Fe) is one of the heavy metals with high levels in Sidoarjo mud and is toxic to cultivated plants. This study aims to measure the potential of Centong Cactus (Opuntia cochenillifera) as a candidate for soil remediation agent in Sidoarjo Mud contaminated land by using soil Fe uptake and plant growth as indicators. This research was carried out for 3 months from December to March 2022 in the yard of Gebang Village, Sidoarjo District. This study used the correlational regression method to determine the relationship between 0-30% content of Sidoarjo mud with Fe content and various plant growth parameters. The data were statistically processed using regression at the 95% confidence level to determine the significance of the effect and the correlation between the mud content and the decrease in soil Fe content and plant growth. The results showed that there was an increase in soil Fe uptake by plants and a decrease in plant growth with an increase in silt content in the soil of the growing media. O. Cochenillifera has the potential as a candidate for phytoremediation agents that can be applied to areas exposed to Sidoarjo mud, especially for its use to reduce Fe metal levels.

Abstract

This research has made a goal to know the interaction between growing media and Trichoderma sp. and their impact for the growth and production of Javanese Ginseng (Talinum paniculatum Geartn.) This research was carried out in February-May 2022 on the land of Boro Village, Tanggulangin using polybags. The study employs Randomized Block Design with two trial factors. The 1st factor is growing media. Top Soil 100%; Top Soil 50% + Sand 50%; Top Soil 50% Sand 25% + Charcoal Chaff 25%; Top Soil 50% + Sand 25% + Cocopeat 25%. For the 2 nd Factor is Trichoderma sp. Without Trichoderma sp. and with 20ml Trichoderma sp. These 8 combinations of treatment, repeated 3 times. The observed variable is the height of the plant, the number of the leaves, diameter of the stem, the number of the shoots, the weight of the leaf and length of the plant roots. The results showed that between the treatment of growing media composition and Trichoderma sp. there is no real impact on all observation variables. The treatment of growing media composition has a noticeable effect on the height, number of leaves and number of shoots of the Javanese Ginseng plant. The treatment of composition between soil and sand produces the highest plants with the heaviest leaves. While the treatment of giving Trichoderma sp. has an unreal effect on all variables
